HARRY F. RICH, OF CHICAGO, ILLINOIS.

GASEMENT-ADJUSTER.

Specification of Letters Patent.

Patented Apr. 1,1913.

Application filed July 29, 1912. Serial No. 712,137.

To all whom it may concern:

Be it known that I, HARRY F. RICH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certaln new and useful Improvement in Casement-Adpisters, of which the following is a speclficatlon.

My invention relates to casement ad usters and the object of the invention is to provide simple and effective means for looking the easement at any desiredangle. I accomplish this by the mechanism 1llu strated in the accompanying drawings 1n which- Figure 1 is a perspective view of a casement to which my device is applied Fig. 2 is a plan view of the parts shown in Fig. 1. Fig. 3 is a vertical sectional view of the preferred form of detent. Fig. 4 is a perspective of the locking rod upon which the detent travels.

Similar numerals refer to similar parts in the different views.

The casement 1 is mounted upon the hinges 2 secured to the window frame 3 in such manner as to swing horizontally. In the form illustrated my device is more particularly applicable to a casement so arranged as to swing into the room, although this is not essential to my invention.

In its present form and manner of mounting, the locking rod 5 is .rotatably mounted in the brackets 6 located near the top of the outside of the casement. Longitudinal movement of the rod is prevented in suitable manner, in the present instance, a head 7 being formed at one end of the rod and a lever 8 at the other end just outside the brackets. Said lever is secured to the rod in such manner that the rod may be rotated by swinging the lever to difierent positions. The rod is cylindrical and has a number of notches 10 formed upon one side. Forconvenience, the side containing the notches will be referred to as the top; This, however, is a matter of detail which may be varied without departing from the spirit of the invention.

Slidingly mounted upon the locking rod 5 is a detent the preferred form whereof is shown in detail in Fig. 3. In the form illustrated said detent consists of a plunger 12 provided on the under side with a finger 13 adapted to enter the notches 10 and prevent movement of said plunger lengthwise of the rod. Said plunger fits slidingly within the vertically arranged housing 14 which is closed at the top and contains a coiled compression spring 15 between the plunger and the top of the casing. Said spring constantly urges the plunger and finger toward rod 5. At the side of the housing are lugs 17 which carry a pin 18 by which said housing and the arm 20 are articulately connected. At the opposite end arm 20 is articulately connected to the window frame, for example, by means of the plate 21 secured to the top of the frame.

In operation, when my adjuster is not in active use the locking rod 5 is rotated to such position that the cylindrical un-notched portion is in contact with the under side of the finger 13 on the plunger. This permits the 7 housing 14 to slide lengthwise of the rod and consequently permits the easement to be swung to any desired position. When the desired position of the easement is reached the operator, grasping the lever 8, rotates the rod to such position as to bring the notched surface upward. By then swinging the easement a trifle to the right or left one of the notches 10 will be brought into register with the finger 13 whereupon the spring 15 will force the finger into the notch beneath and hold it there. This will prevent the housing from sliding along the locking rod and consequently prevent the casement from being swung in either direction from its position. When the operator desires to release the easement he rotates the locking rod a quarter turn or so in either direction and thus rotates the notched portion of the rod away from the finger, which releases the rod. The casement is then free to swing as before.

It will be seen that with my device all thumb screws, set screws, latches and kindred devices are avoided. It will also be noted that the device is operable from the outer end of the locking rod which will ordinarily be located at or near the free edge of the casement. Consequently the operator does not need to reach in toward the hinges but will find the operatinglever'ready to hand at all positions of the casement. WVhen mounted, as illustrated in the present drawings, the entire mechanism will lie on the outside of the easement when closed, thus avoiding unsightly appearance from the inside of the room. On account of its location at the upper edge of the casementthe preferred positionthe mechanism, when the easement is closed will be completely sheltered under the window frame and will be thereby very largely protected from the weather.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is-

1. In a casement adjuster, the combination of a notched rod rotatably mounted upon the casement, a housing slidingly mountedupon said rod, an arm articulately connected at one end to the housing and at the other end to the window frame, said arm preventing rotation of the housing about the axis of the rod, and a spring urged finger pressing upon said rod and adapted to enter the notches therein when said notches are turned toward it.

2. In a casement adjuster, the combination Copies of this patent may be obtained for ofa notched cylindrical rod arranged horizontally upon the casement and adapted to rotate about its axis, said rod being longitudinally fixed, a lever on said rod for rotating it, a housing slidable upon said rod, a spring pressed finger in said housing con stantly urged toward the rod and adapted to enter the notches therein to prevent sliding of the housing along the rod, and. a rigid arm connecting the housing with the window frame.

In witness whereof, I have hereunto subscribed my name in the presence of two witnesses.
